Erik Kjellberg, Uppsala University

In 1987, Professors Erik Kjellberg and Kerala Snyder made the decision to produce a complete catalogue of the collection as a joint project between the musicology departments of Uppsala University and the Eastman School of Music, University of Rochester (USA), using a computer database. Planning for the project began in Rochester in 1988, it was launched in Uppsala in June, 1991, and reported in Computing in Musicology: An International Directory of Applications in 1992. 

The stated goals of the Project were twofold: to produce a database catalogue of the collection and to provide the students with opportunities to work with both the manuscripts of the collection and computer databases as well as to participate in international cooperation and exchange. Three distinct stages of the Project were envisioned. Stage 1 consisted of designing the database and entering the existing catalogued information into it: this was done both in Rochester and Uppsala. In Stage 2 the individual manuscripts would be examined and the data corrected and amplified. In Stage 3, individual scholars would refine the data as they studied particular aspects of the collection, work that will continue into the future. 

During Stage 1, led primarily by Professor Kerala Snyder, a relational database was developed on personal computers, using successively the programs D-Base 3, Paradox, and Access, and moving finally to the web-based database at the Göteborg Organ Art Center. Very little funding was available at this stage, and students at Rochester and Uppsala volunteered their labor to enter the material from the existing catalogues into the master database, containing one entry per source item, and linked subsidiary tables. A grant from Uppsala University made it possible for three musicology students from the Eastman School of Music to travel to Uppsala in 1995 to begin work on Stage 2. Among the students who worked on the Project in these early stages were Mary Frandsen, Kia Hedell, Lars Berglund, Susanne Fåhraeus, Birgit Heinz, Bernt Malmros, Lena Bergquist, Mats Åberg, Britt-Marie Hogmalm, John Sheridan, Stan Pelkey, Peder Kodsas, Andrus Madsen, and Tom Elston. 

In 2003 The Bank of Sweden Tercentenary Foundation made it possible to bring Stage 2 of the Düben Project to its conclusion under the leadership of Professor Erik Kjellberg. This work consisted primarily in adding data to subsidiary tables devoted to the individual parts and tablature volumes, watermarks, and handwriting. Thanks to the cooperation of the Uppsala University Library, it became possible to add to the original plan the scanning of every page of the manuscript sources, with the images now linked to the catalogue. The main encoding and scanning work for Stage 2 has been done by fil.dr. Lars Berglund, fil.dr. Kia Hedell, and during the final year of the project, Juliane Peetz, David Jansson, Katharine Leiska, Alison Hurst and Anne Reese. The database structure has continuously been refined by our data consultant, Master of Civil Engineering Carl Johan Bergsten, GoArt (Göteborg) in close connection with the participants in the project, notably Lars Berglund and Jan Johansson, who has also implemented the current system at Uppsala University. Dr. Peter Wollny, of the Bach-Archiv, Leipzig, has acted as special consultant to the Project during Stage 2. 
With the near completion of Stage 2 in September 2006, the database moved to the server at Uppsala University and became available to the general public. The work of scanning and entry of Stage-2 data will continue until it is completed. We further acknowledge that some mistakes taken over from the previous catalogues may still remain, and we invite corrections from outside scholars. We also hope that they will contribute to Stage 3 of the Düben Project by supplying additional information from their own research, which will be gratefully acknowledged. Scholars wishing to do so are asked to contact Lars Berglund, at the Department of Musicology in Uppsala, at this mail address: duben@musik.uu.se. 

The Düben Collection

The Düben Collection contains ca. 2,300 musical works in manuscript from the 17th and early 18th centuries and some 25 prints. It was donated to the Uppsala University Library in 1732 by Anders von Düben. 
The collection derives it name from the family Düben whose members served as Hofkapellmeister at the Royal Swedish Court from 1640 to ca. 1726 (Anders Düben 1640-62, his son Gustav Düben 1660-90 and his sons Gustav, 1690-98 and Anders 1698-ca. 1726). 
Gustav Düben the elder (1628-90) is generally regarded as the main assembler of the collection, which contains vocal and instrumental works by more than 300 composers from Germany, Italy, France, Poland, England, the Baltic countries and Sweden, besides a large number of anonymous works. It is most llikely that the collection represents what remains of the music library from the Swedish Royal Court during the reign of Queen Christina (1644-54), Charles X Gustav (1654-60), Charles XI (1660/1672-97), and Charles XII (1698-1718). 

The Düben Collection was catalogued for the first time in the 1880s by the librarian Anders Lagerberg, who assigned to its various manuscripts the library signatures still in use. The importance of the collection for 17th-century European music history was soon recognized, and many of its works have since been published in modern editions and discussed in the scholarly literature. Folke Lindberg prepared a detailed catalogue of the vocal works (1946) and Erik Kjellberg catalogued the instrumental works (1968), but neither was published. Bruno Grusnick began a chronological catalogue of the vocal works (Svensk tidskrift för musikforskning, 1964 and 1966), but it extended only until 1680. Jan Olof Rudén made catalogue cards of all music preserved in manuscript at Uppsala university for RISM and a detailed study of the watermarks in the collection (1968), but it covered only those with the foolscap design. Despite all this research, a published catalogue of the Düben Collection did not yet exist. 

Basic Search

Basic Search uses mainly information related to Work. Clicking on DCDC Basic Search in the left columns will bring up the search form, where you are presented with a number of different search fields. At least one field has to be specified, but you can enter criteria in several or all fields. No individual field is mandatory. 
Composer can be specified in several different ways: 
If you click in the top leftmost Composer box you will see a list of all composer names in the database. Select the Composer name you want by clicking on it. 
In the smaller box to the right you can type in the beginning of the composer's name, and the system will present you with the composer name that matches your typing. 
The next three search form lines for Composer gives you the possibility to enter part of the name or the names you are looking for. There are two lines where you can enter either the initial characters of the name(s), or characters that should be contained in the name(s). You can user one or two conditions, and combine them with AND or OR. 
The search process is not case sensitive. 
Title search functionality is similar to that for Composer 
Vocal/Instrumental lets you select from a pop up either Vocal (meaning that there is at least one vocal part), Instrumental (meaning that there are only instrumental parts in the Work), or blank (the default, meaning that you do not want to select on this criterion) 
Key lets you select from a pop up the key of the part or blank (the default, meaning that you do not want to select on this criterion) 
The fields for No of voices and No of instruments allows you to key in how many voices and/or instruments you wish to limit the search to. 
Search criteria regarding Scoring are handled just like for Composer and Title. The scoring information is in fact stored in another table, but is matched against the Work information. An explanation of scoring abbreviations can be found here. Other instruments are specified with their full names (eg. "chitarra"). 
You can specify the sorting order for the results by choosing either Composer or Title. 
When you are done with specifying your search criteria, hit Find and you will be presented with a list of all Works that fulfil your criteria. 

Advanced Search

Advanced search allows for combined searches regarding Works, Source, Parts and Volume. For each category a number of search criteria can be specified, and these are combined with an AND condition between the tables involved. 

Special Searches

DCDC contains a large number of pieces of information that can be combined, linked and searched in different ways. We hope that the functions provided through Basic and Advanced Search can help different categories of users to find the information they are looking for. Still we expect that there will be situation where there is a need to utilize the DCDC information in new ways. Some situations can probably be handled by creating special DCDC search function, and the Department of Musicology can assist in creating such functions. The idea is to make these functions so general that they also can be used by others, and here we list some of the special search functions that have been developed.
